The enzymatic reduction of Cr(VI) to Cr(III) by Cr(VI) resistant bacteria followed by chemical precip- itation constitutes the ChromeBac™ system. Acinetobacter haemolyticus was immobilized onto carrier material inside a 0.2 m3 bioreactor. Neutralized electroplating wastewater with Cr(VI) concentrati...
